Hiring the right consultant is tricky. Beyond checking credentials, you should consider the following:
Will this person represent our company well?
Do our values align?
Will I enjoy working with this person?
To have a great client-consultant partnership, you should say 'yes' to all three. I approach my work with these values in mind...
Honor tradition and challenge status quo.
Admit and learn from mistakes.
Wag more, bark less.
Listen for what goes unsaid.
Don't wait to be asked.
Life is hard. Humor is the antidote!
